Experiment File

You can disable a study in the expt.xml file by adding the disable="URL" attribute to the study.  Anyone who tries to take the study will instead be sent to the URL that you specify.  Using this can be an advantage for private link studies, where you want people clicking the link after the study has ended to get a page telling them that the study is expired.  For example, to send someone trying to take your study to a more important study:

<Study id="Demo.Skin" datagroup="std" disable="http://humanoralien.com">

A new feature is ready for testing by lab members- a study progress bar.  This bar will appear at the top of the window as participants take the study, showing how much they have completed.  You can also set the weight of each task.  The weight will determine how much the bar will go up after the participant completes the task.  So if you have 100 total weight and the participant completes a 8 weight task, the progress bar will increase by 8%.  Just change your expt.xml file to use

<Task id="startpage">/common/en-us/html/InstructionsProgressBar.jsp</Task>

You can use the <Done> tag in your study expt.xml file to show that all important manipulations / measures have been completed by the participant.    Do so by adding <Done/> to the map, as follows:

<Map>

<Task id="startpage"/>

<Task id="iata"/>

<Done/>

<Task id="debriefing1"/>
<Task id="debriefing2"/>

</Map>
